SPECIFICATION forming part of Letters Patent No. 729,334, dated May 26,1903.

Application filed $eptember 9, 1902. Serial No. 122,733. (No model.)

To all whom it minty concern:

Be it known that I, FRANK A. HALL, J r., a citizen of the United States,and a resident of Montclair, in the county of Essex and State of NewJersey, have invented new and useful Improvements in Sprin g-Frames, ofwhich the followingis a full, cleanand exact description.

This invention relates to a frame for the woven-wire springs used in bedconstruction.

The object of the invention is to render these frames thoroughly rigid.I-Ieretofore it has often been a disadvantage that the frames areparticularly liable to rupture, slight strains being sufficient in somecases to make the frame quite useless. This weakness is mainly presentin the connection between the side bars and the brackets, and myinvention resides in forming 011 these parts peculiar i11- terengagingwedge-like surfaces which are bound firmly together, thus to prevent anytwisting or working movements of the parts.

This specification is a specific description of one form of myinvention, while the claims are definitions of the scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the invention, and Fig. 2 is a sectionon the line 5 5 of Fig. 1. f indicates the bracket, which has an arm fto engage the bed-frame and support the spring-frame thereon.

9 indicates the end rail, and 71. the spring. *6 indicates the side railof the spring-frame, and 7c a bolt which extends through the end of theside rail and into the bracket and through the end rail, thus clampingthese parts i, f, and g together. Formed in the side railvl is anopening 1', which serves to receive the bolt and also to receive thetapered stud f which is formed on and projected downward from the bottomof the bracket f.-

This stud being tapered is'forc'ed by the pressure of the bolt 70 intoone end of the opening 2', and thus the before-mentioned wedge-like en-'gaging surfaces are provided.

This construction operates to prevent wrenching and twisting the partsof the frame, thereby holding said frame rigid in every respect.

Various changes in the form, proportions, and minor details of myinvention may be resorted towithoutdeparting from the spirit and scopethereof. Hence I consider myself entitled to all such variations as maylie within the scope of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A spring-frame for beds comprising a side rail"having an opening in its side, a

bracket having a tapered stud projecting downward from the brackettransversely of the side-rail into the opening thereof, said bracketalso having a projected arm capable of engaging the bed to sustain thespringframe thereon, and a bolt engaged with the bracket and side railand serving to draw the side rail up against the bracket and wedge thetapered stud into the said opening in the side rail. 2. A spring-framefor beds comprising a side rail having an opening in its side, a brackethaving a tapered stud projecting downward from the bracket transverselyof the side rail into the opening thereof, said bracket also having aprojected arm capable of engaging the bed to sustain the springframethereon, an end rail lying on the side of the bracket opposite the siderail and a bolt passed through the end rail, bracket and side rail andserving to draw said parts together and wedge the tapered stud tightlyinto the said opening in the side rail.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK A. HALL, JR.
